Re: 350/290 Crate vs. stock 72 350 4bbl power?
From what I have heard is that it has a lot of camshaft for the compression ration - still ~8.5:1 with dished pistons and 76cc heads. That makes the low end kind of weak.
The marine comment has more to do with the overlap of the camshaft and water reversion - i.e. sucking water into the engine. Most marine engines have water cooled exhaust and that limits camshaft choices.
